If you're seeking top-notch microphone quality and superior sound for gaming, music, and calls, the EPOS PC38X stands out, particularly with its open back design that provides a broad soundstage; however, it lacks wireless functionality and noise isolation, making it less versatile for travel or noisy environments. In contrast, the JBL Live 670NC is wireless, supports active noise canceling, and is optimized for air travel and portability, though it delivers lower overall sound quality, which might impact the experience for critical listening or immersion in gaming or TV. Choose the EPOS for home use and premium audio and the JBL for versatility and use on the go. Give Feedback
